How to iterate any Map in C#
C# has no built-in Math type. For the same, use a Dictionary.
Firstly, create a Dictionary −
Dictionary<string, int> d = new Dictionary<string, int>(); d.Add("keyboard", 1); d.Add("mouse", 2);
Get the keys −
var val = d.Keys.ToList();
Now, use the foreach loop to iterate over the Map −
foreach (var key in val) { Console.WriteLine(key); }
To iterate it, try to run the following code −
Example
using System; using System.Collections.Generic; using System.Linq; class Program { static void Main() { Dictionary<string, int> d = new Dictionary<string, int>(); d.Add("keyboard", 1); d.Add("mouse", 2); // get keys var val = d.Keys.ToList(); // sort val.Sort(); // displaying sorted keys foreach (var key in val) { Console.WriteLine(key); } } }
Output
keyboard mouse
